Davey Lopes

With Davey's departure the team has another hole to fill.

He helped the team effectively use the running game more than any time in recent memory. 
This helped to set up homerun counts for batters and to produce small-ball runs as well.

His also worked with the outfielders, leading them to be in position to attain those generally solid fielding percentages.

We will have to see who replaces him and how that affects the team next season.
